ANCHOR.

To all whom itmay concern: i o o a Be it known that I, WILLIAM M. BATE-MAN, a citizen of'the United States, residing at Chester, in the countyof Delaware and State of Pennsylvania, have invented certain new anduseful Improvements in Anchors, of which the following is aspecification.

My invention the type of anchor shown in the United States Patent No.961,095, June 1 1, 1910.

One object of my present invention is to provide an anchor in which thehead and connected flukes are .pivotally connected with the shank and toso construct the parts of my improved anchor that shearing actionbetween the head and shank will be reduced to a minimum.

Another object is to so construct my improved anchor that the parts canbe readily made and assembled.

A still further object is to so construct my improved anchor that theflukes will be pro vided with integral veins which are so constructedand arranged that the weighing action of the anchor will cause saidveins, by engagement with the side of a ship, to be moved to move saidflukes substantially into alinement with the shank.

These objects, and other advantageous ends which will be describedhereinafter, I attain in the following manner, reference being had tothe accompanying drawings in which Figure 1 is a front elevation of myimproved anchor,

Fig. 2 is an inverted plan view of Fig. 1,

Fig. 3 is a side view of Fig. 1,

Fig. 41 is a sectional view through the head and taken on the line H ofFig. 1, the shank being omitted for clearness,

Fig. 5 is a fragmentary section through the head and taken on the line5.5 of Fig. 3,

Fig. 6 is a fragmentary face view showing the lower end of said shank,and

Fig. 7 is a side view of Fig. 6.

Referring to the drawings, 8 represents the head of my improved anchorand is provided with lateral flukes 9. The head 8 has a cavity 10extending upwardly from its bottom and a segmental opening 11 at itstop, said segmental opening communicating with the cavity 10. The head 8at both sides of the opening 11 is undercut to provide arrelates toimprovements .in

cuate; grooves 13 which communicate with the, avity 10, the grooves incross section be: smoothly rounded, as clearly shown in Fig; 5,, so astobe free of any sharp edges which would start afracture or form shear"ing, members. Saidundercut portion of. the. head 8 from the axesof thearcuate grooves,

extending in. substantially parallel arrange .mentun a dlrection awayfrom said arcuate grooves to provide substantially parallel extensionsof said grooves. The shank 1 1 has its extreme lower end 15 circular inlongitudinal section.

Two oppositely disposed lugs 16 and 1.7 interceptthe end 15 and flareoutwardly. These lugs are adapted to fit within the undercut arcuategrooves 13 of the head and a pin 18 is riveted within the head 8 andextends across the cavity 10. This pin 18 is so located between theparallel extensions of the undercut grooves 13 that the curved end 15 ofthe shank rests and rolls thereon at all times while the lugs 16 and 17snugly rotate within the arcuate portions of said grooves 13 and thefact that the curved end 15 of the shank is curved throughout its entirewidth, as shown in Fig. 5, causes a good bearing surface for engagementwith the pin 18. The pin 18 thus retains the shank in such position thatthe lugs 16 and 17 are always within the undercut grooves 13. This is animportant improvement of my present invention since there is practicallyno relative movement either in an upward or downward direction betweenthe lugs 16 and 17 and the head 8; the only movement permitted is apivotal movement which is limited to the extent of the width of theopening 11.

Each of the fiukes 9 is provided with oppositely disposed integral veins19 and these veins extend beyond the peripheral surface of the head, asclearly shown in Figs. 2 and 3. The outer ends of these veins engage theside of the ship during the raising or lowering of the anchor and causethe flakes to be held in substantial alinement with the shank so thatthey will not project at an abrupt angle.

WVhile I have described my invention as taking a particular form, itwill be under stood that the various parts of my invention may bechanged without departing from the spirit thereof, and hence I do notlimit myself to the precise construction set forth, but

consider that I am at liberty to make such changes and alterations asfairly come within the scope of the appended claim.

Having thus described my invention, What I claim as new and desire tosecure by Letters Patent is:

An anchor having a head provided with fluke-s and including a cavityextending upwardly from its bottom, said cavity including two oppositelydisposed undercut grooves arcuate at the innermostpart and havingsubstantially parallel portions extending from said arcuate portionstoward the bottom of said cavity; a pin extending across said cavitybetween said parallel por. tions of the undercut grooves; and a shankCopies of thio patent'may be obtained for having a portion extendingthrough said opening into said cavity, the bottom of said shank beingcircular in cross section and adapted to roll throughout its entirewidth upon said pin, said end portion of the shank having lateral lugsfitting the arcuate portions of said undercut grooves and having theirbottom portions in" rolling contact with said pin; substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
